I plan on adding a HOB refugium to my 20 gallon soon-to-be reef. I'm not sure if I will be using either a 4" DSB or Miracle Mud for substrate. I have heard that the lower the flow for a refugium--the better.

Soooo.... The CPR is overpriced as heck.

I was thinking about giving the Finnex HOB fuge a try since it comes with a LED fixuture. It comes with either an air pump that offers right under 5gph or a water pump that offers 40gph.

Personally, I'd like to use an air pump since it won't clutter the tank. I've already got a Maxi Jet 1200 in there for the AquaC Remora, and that's already an eye sore.

Can anyone clear up this flow rate ignorance that I have?

I posted this on a local forum about a week ago. Lots of great people on there who are very smart and have amazing tanks. Not one person replied. IRONY?

Thanks,
Allen
